Product details
Overview
SN74LVC1G07DBVTG4 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V–5.5V VCC operation. It delivers ±24mA output drive at 3.3V, supports 5.5V-tolerant I/O, and achieves 4.2ns max propagation delay at 3.3V - enabling wired-OR logic and level translation in space-constrained consumer audio and embedded control interfaces.
For engineers reviewing the SN74LVC1G07DBVTG4 datasheet, SN74LVC1G07DBVTG4 pinout, SN74LVC1G07DBVTG4 application, or SN74LVC1G07DBVTG4 equivalent, key selection criteria include open-drain sink capability (32mA max), Ioff support for live insertion, 5.5V input tolerance, and SOT-23-5 package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The SN74LVC1G07DBVTG4 implements a single CMOS buffer stage with open-drain output topology, requiring an external pull-up resistor to define high-level voltage. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current and enabling partial-power-down system architectures.
It operates across 1.65V–5.5V supply range while accepting input voltages up to 5.5V regardless of VCC, supporting bidirectional level translation between disparate voltage domains. Propagation delay is specified down to 1ns (min) at 5V and remains ≤4.7ns (max) over –40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic families without level shifters. |
| IOL Max Sink Current | 32mA at 4.5V - sufficient to directly drive LEDs, relays, or multiple CMOS inputs in wired-OR configurations. |
| tpd Max | 4.2ns at 3.3V - supports signal integrity in high-speed digital control paths up to ~100MHz clock-equivalent rates. |
| Ioff | ±10µA max - ensures safe hot-plug operation and prevents damage during power sequencing mismatches. |
| VI/VO Tolerance | Up to 5.5V - allows inputs/outputs to exceed VCC, enabling robust interfacing with legacy 5V peripherals. |
| ESD Rating (HBM) | 2000V - meets JEDEC JESD22-A114A, reducing risk of field failure in handling and assembly. |
| Operating Temp | –40°C to 125°C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9mm × 2.8mm body size, 2.9mm × 1.6mm footprint, 0.95mm max height, lead pitch 0.95mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | No internal connection | Unused pad; must be left floating or grounded per layout best practice - no electrical function. |
| 2 - A | Input | CMOS-compatible digital input; 5.5V tolerant, accepts VIH ≥ 0.65×VCC (min) for reliable logic-high recognition. |
| 3 - GND | Ground reference | Primary return path for output sink current and internal logic; requires low-impedance PCB connection. |
| 4 - Y | Open-drain output | Active-low output node; requires external pull-up to define VOH; sinks up to 32mA when driven low. |
| 5 - VCC | Power supply | Supplies internal logic and output driver; bypass with 0.1µF capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5.5V-tolerant I/O | Enables direct connection to 5V buses while operating from 1.8V/2.5V/3.3V supplies - eliminates discrete level translators. |
| Ioff protection | Prevents current backflow during power-down or hot-swap events - critical for modular systems and battery-backed subsystems. |
| Wired-OR/AND capability | Multiple SN74LVC1G07DBVTG4 outputs can share one pull-up resistor to implement active-low OR or active-high AND logic functions. |
| Ultra-low ICC | 10µA max quiescent current - reduces standby power in always-on IoT nodes and portable media devices. |
| High-speed tpd | 4.2ns max at 3.3V - maintains timing margins in compact microcontroller GPIO expansion and sensor interface chains. |
Applications
| LED Driver Interface | GPIO Expansion for MCU |
|---|---|
|
Use Scenario: Driving high-brightness indicator LEDs in portable media players and DTV front panels where board space and BOM count are constrained. IC Role / Device Role: Open-drain buffer sinking LED current through cathode; pull-up defines logic-high voltage independently of VCC. Use Value: Eliminates need for discrete transistor + resistor solution; 32mA sink capability supports multi-LED strings without external drivers. |
Use Scenario: Extending limited GPIO count on ARM Cortex-M microcontrollers in smart home hubs and industrial gateways. IC Role / Device Role: Level-translating buffer isolating MCU I/O from higher-voltage peripheral buses (e.g., 5V sensors or displays). Use Value: 5.5V I/O tolerance and 1.65V–5.5V VCC range allow seamless integration across mixed-voltage designs without additional translation ICs. |
| Wired-OR Power Sequencing | Reset Signal Aggregation |
|
Use Scenario: Implementing fault-safe power-good arbitration across multiple DC/DC converters in SSD and embedded PC power rails. IC Role / Device Role: Each converter drives its own SN74LVC1G07DBVTG4 output low upon fault; shared pull-up yields active-low OR result. Use Value: Hardware-based, zero-latency fault detection without firmware intervention - improves system reliability and boot robustness. |
Use Scenario: Combining reset signals from watchdog timers, brown-out detectors, and manual reset buttons in network projectors and DLP systems. IC Role / Device Role: Open-drain outputs tied together to form active-low reset bus; any asserted input forces global reset assertion. Use Value: Eliminates need for dedicated reset supervisor IC; supports asynchronous, glitch-free reset aggregation with minimal component count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Same silicon, 3000-unit tape-and-reel vs. 250-unit small reel; identical electrical specs and SOT-23-5 package. | Optimized for high-volume production runs rather than prototyping or low-quantity validation. | Select DBVR for cost-sensitive volume manufacturing; DBVTG4 preferred for engineering samples and design-in flexibility. |
| 74LVC1G07GW,125 (Nexperia) | Pin-compatible SOT353-5 package; same 1.65–5.5V VCC, but lower max IOL (24mA @ 3.3V) and higher tpd (5.5ns max). | Suitable for less demanding drive/current requirements; not recommended for 32mA LED or relay loads. | Choose when sourcing diversification is required and full 32mA sink is not needed - verify thermal derating at target ambient. |
Compared with SN74LVC1G07DBVTG4, SN74LVC1G07DBVR offers identical performance in bulk packaging, while 74LVC1G07GW,125 provides second-source availability with minor trade-offs in drive strength and speed - both require no PCB changes but differ in supply chain resilience and thermal margin.

FAQ
What is the maximum sink current capability of the SN74LVC1G07DBVTG4?
The SN74LVC1G07DBVTG4 supports up to 32mA sink current at VCC = 4.5V, as specified in the Absolute Maximum Ratings table. At 3.3V, it delivers ±24mA, making it suitable for driving LEDs, small relays, or multiple CMOS inputs in wired-OR configurations without external amplification.
Does the SN74LVC1G07DBVTG4 support level translation between different voltage domains?
Yes, the SN74LVC1G07DBVTG4 supports bidirectional level translation: its inputs and open-drain output accept voltages up to 5.5V independent of VCC, enabling use between 1.8V, 2.5V, 3.3V, and 5V logic domains. No external biasing is required beyond the pull-up resistor on the Y pin.
Can the SN74LVC1G07DBVTG4 be used in hot-swap or partial-power-down systems?
Yes, the SN74LVC1G07DBVTG4 features Ioff circuitry that disables outputs when VCC = 0V, limiting Ioff to ±10µA. This prevents damaging back-current flow during live insertion or mismatched power sequencing - a key requirement for modular industrial and telecom equipment.
What is the operating temperature range for the SN74LVC1G07DBVTG4?
The SN74LVC1G07DBVTG4 is rated for –40°C to 125°C operation when packaged in the SOT-23-5 (DBV) variant. This extended industrial temperature range qualifies it for under-hood automotive modules, industrial PLC I/O, and high-ambient embedded computing applications.
Is a pull-up resistor required for the SN74LVC1G07DBVTG4 output?
Yes - the SN74LVC1G07DBVTG4 has an open-drain output (pin 4, Y), which can only actively pull low. A pull-up resistor to a defined voltage rail (e.g., 3.3V or 5V) is mandatory to establish a valid high logic level. Typical values range from 1kΩ to 10kΩ depending on speed and load capacitance requirements.
